Congrats on quitting smoking-this will be favorable for your health long-term. It sounds like you likely have bronchospasm with some airway inflammation that can be treated with inhalers-both a bronchodilator inhaler and a steroid inhaler. These will likely be short-term as your airways adjust to no smoking. So, you should see your doctor and you may need to be seen by a lung doctor. Good luck!ch

Common in those who recently quit smoking: Globus Hystericus. Formerly thought to be all Psychological, but now considered to be part physiological. Feels like a ball in throat & tightness of the neck region. Oft mild cough, but no distinct signs of infection. Usually last several weeks & fades; sometimes months. Probably tension in certain muscles of upper airway. No serious consequences.
